Radio frequency identification (RFID) excelled in automatic identification and data collection industry through its speed, agility and endurance. RFID of objects and people and remote control of devices has become very popular in logistics, inventory management and bio-engineering applications. RFID system which works on the basis of alternating electromagnetic fields mostly consists of two vital components - a RFID tag (transponder) and a RFID interrogator (reader). As this is a contact less technology, both of these components should have independent antennas to transfer data among them. This paper reviews the recent developments of the tag antennas focusing different technologies and architectures in recent years on the basis of recent published manuscripts and patents. Moreover, projections on future development trends are also provided.
